TRITD2AV1G065030 — Triticum turgidum subsp. durum

Summary

TRITD2AV1G065030, designated BEH1 (also known as TtBZR2, BES1, BZR1), encodes a protein with BZR and BES1_N domains on durum wheat chromosome 2A. The product is annotated with transcription regulator activity, sequence-specific DNA binding, and multiple enzymatic annotations including phosphatidylethanolamine-sterol O-acyltransferase and sucrose synthase activities. BEH1 is associated with brassinosteroid signaling pathways, including BZR/BES-regulated transcription, phosphorylation, and interactions with PIF4 and 14-3-3 proteins. The gene is linked to regulation of vernalization response, ethylene biosynthesis, and jasmonic acid/ethylene-dependent systemic resistance. Associations include numerous agronomic traits such as plant size, leaf area, root morphology, seed and grain characteristics, flowering time, bacterial disease response, and stress tolerance. Related genes in other species are linked to plant height, grain size, heading date, and sheath blight resistance.
